1 INTRODUCTION

The SVAN 958 is digital, four channels 0.5 Hz to 20 kHz signal analyser including Type 1 sound level meter (meeting IEC 61672-1:2002) and vibration meter (meeting ISO 8041:2005). It is an ideal choice for the Human Vibration (according to the ISO 2631-1, 2 & 5 and ISO 5349-1 & 2 standards) and noise measurements in the occupational health and safety monitoring tasks. All required weighting filters, transducers and adapters for triaxial Whole-Body and triaxial Hand-Arm vibration measurements (VM) are available with this instrument.

Each of four channels can work simultaneously with independently configured input (transducer type), filters and RMS detector time constants (e.g. simultaneous three-axis measurement of the Whole-Body vibration and noise dose).

Four channels allow parallel measurements with independently defined filters and RMS detector time constants in every channel. Additionally, in the case of sound measurements (SM), each channel calculates simultaneously the results in three independent profiles. Each channel (and profile for SM) provides "multidimensional" analysis of measured signal (like LEQ, LMax, LMin, LPeak, SPL, SEL in the case of SM or RMS, PEAK, PEAKPEAK (PP), VDV, MTVV in the case of VM). Advanced time-history logging, in non-volatile 32 MB internal memory, provides very powerful measurement capability. The external USB Memory Stick extends this facility almost unlimitedly. Results can be easy downloaded to any PC using standard USB (or optional RS 232 and IrDA) interface and SvanPC software.

Using computational power of its digital signal processor the SVAN 958 instrument can perform advanced frequency analysis simultaneously to the meter mode: - real time 1/1 or 1/3 octave analysis including statistical calculations - FFT analysis including cross spectra.

Reverberation Time measurements, noise dosimeter and rotation speed measurements are available as options for the SVAN 958 instrument.

The time-domain signal recording on the external USB memory stick is also available as an exceptional option.

Fast USB 1.1 interface (12 MHz) creates real time link for the PC "front-end" application of the SVAN 958. The instrument can be fully remotely controlled.

The instrument is powered by four AA standard or rechargeable batteries (separate charger is required). The powering of the instrument from the external DC power source or the USB interface is also provided.

Robust case and light weight design accomplish the exceptional features of this new generation instrument.

2 MANUAL CONTROL OF THE INSTRUMENT

The control of the instrument is developed in the fully "conversational" way. The user can "programme" the operation of the instrument selecting the proper option from the MENU. Thanks to it, the number of the control push-buttons of the instrument is reduced to nine.

2.1 Control push-buttons on the front panel

On the front panel of the instrument, there are located the following control push-buttons: 1. , (), [] 2. , (), [] 3. , [Markers] 4. , [Markers] 5. 6. 7. 8. 9.

The name given in brackets (...) denotes the second push-button function which is available after pressing it in conjunction (or in sequence) with the push-button. The name given in square brackets [] denotes the push-button function which is available after pressing it in conjunction (or in a sequence) with the push-button.

Control push-buttons of the SVAN 958 instrument

The second function of a push-button (written in red colour on a push-button) can be used when

the push-button is pressed. This push-button can be used in two different ways: as SHIFT in the keyboard; both push-button must be pressed in parallel as 2nd Fun; this push-button can be pressed and released before pressing the second one

pressed in conjunction with enables the user to enter the MARKERS on the logger plots during the measurement.

SVAN 958 USER MANUAL .

2-2

Notice: The operation of this push button can be set as the Shift mode or the 2nd Fun. mode in the SHIFT MODE (path: MENU / SETUP / KEYBOARD SETUP / SHIFT MODE), see Chapter with the SETUP list description.

This push-button enables one to choose the third push-button function in the case of [] and [] push-buttons. In order to select the third function user must press the and the second push-button simultaneously.

This push-button enables one to start the measurement process, when the instrument is not

measuring or to stop it, when the instrument is measuring. It is also possible to set such mode of this push-button, in which in order to start or stop the measurements the user has to press it simultaneously with the one.

Notice: The changing of the push-button mode is performed in the START/STOP (path: MENU / SETUP / KEYBOARD SETUP / START/STOP), see Chapter with the SETUP list description.

Notice: The simultaneous pressing of the and push-buttons switches the instrument on and off.

This push-button enables one to enter the selected operation mode or to confirm control options. Some additional functions of this push-button will be described in the following chapters.

() This push-button (pressed together with the one) enables the user to enter the main list

containing six sub-lists: FUNCTION, INPUT, DISPLAY, FILE, SETUP and AUXILIARY FUNCTIONS. Each of the mentioned above sub-lists consists of the sub-lists, elements and data windows. These main sub-lists will be detailed described in the following chapters of the manual. Double pressed push-button enters the HISTORY list containing eight last opened sub-lists. It often speeds up the control of the instrument.

[] This push-button (pressed together with the push-button) enables the user to save

measurement results as a file in the internal instruments memory or on the USB memory stick. There are two ways of saving a file: with AUTO NAME option - saving a file with the name automatically increased by one (e.g. JAN0, JAN1, JAN2) or save a file by editing its name in the FILE NAME position (see Chapter with the FILE list description).


2-3

This push-button closes the control lists, sub-lists or windows. It acts in opposite to the

push-button. When the window is closed pressing the push-button, any changes made in it are (in almost all cases) ignored.

[] This push-button enables one to break temporary the measurement process. The subsequent

pressing of the push-button deletes the measurement result from the last one second. Up to fifteen last seconds of the measurement can be cancelled in this way.

, These push-buttons enable one, in particular, to:

select the options in an active position in the "horizontal direction" (e.g. filter: LIN, A, C or G, Integration period: 1s, 2s, 3s, etc.)

select the measurement result to be displayed (e.g. PEAK, MAX, MIN, etc.) in one-channel and multi-channel modes of results presentation)

control the cursor in SPECTRUM, LOGGER and STATISTICS modes of results presentation select the position of the character in the text edition (i.e. in the FILE NAME menu) switch on/off markers 2 and 3 switch on/off the BACKLIGHT of the display ( + pressed together)

(, ) The , push-buttons pressed in conjunction (or in sequence) with the enable

the user, in particular, to: speed up the changing of the numerical values of the parameters (i.e. the step is increased from 1

to 10 in the setting of START DELAY - path: MENU / INPUT / MEASUREMENT SETUP / START DELAY)

insert or delete a character in the text edition modes change the statistics class (the number displayed after the letter L) in one-channel and multi-channel

modes of results presentation Some other possible reactions of the instrument on the pressing of these push-buttons

will be described in details in the following chapters.

,

The , push-buttons enable one, in particular, to: change the mode of results presentation select the proper character from the list in the text edition mode switch the active sub-list in a list programme the Real Time Clock (RTC) and TIMER switch on/off markers 1 and 4

Some other possible reactions of the instrument on the pressing of these push-buttons will be described in details in the following chapters.

(, ) The , push-buttons pressed in conjunction (or in sequence) with the enable one,

in particular, to: change the relation between the Y-axis and X-axis of all plots presented on the screen switch the channels and profiles in one-channel and STATISTICS modes of results presentation switch the active channel in multi-channels mode of results presentation

Some other possible reactions of the instrument on the pressing of these push-buttons will be described in details in the following chapters.

[Markers] The Markers enable the user to mark the special events, which occurred during the performed

measurements (i.e. the airplane flight, the dogs barking, the trains drive etc.). In order to enter the markers the logger has to be switched on (path: MENU / INPUT / LOGGER SETUP / LOGGER MODE: ON) and one or more logger options (PEAK, MAX, MIN, RMS in the case of sound measurements and PEAK, PP, MAX, RMS, VDV in the case of vibration measurements) in channels have to be chosen (path: MENU / INPUT / LOGGER SETUP / CHANNEL x). In order to enter the marker the user must press and push-buttons simultaneously during the measurement. The ENTER MARKER window opens and there are four available marker numbers. To choose marker number 1 the user must press push button (number 2 - , number - 3 and number 4 - ).

The ENTER MARKER window closes automatically and chosen marker is activated (after pressing + again active marker number will be highlighted). In order to switch off the marker, the user has to open the ENTER MARKER window and press this push-button, which refers to the marker to be switched off. Up to four markers can be switched on at the same time.

The current state of the markers is indicated in the loggers file and can be used to show them using dedicated presentation software.

2.2 Input and output sockets of the instrument

The measurement inputs, called Channels, are placed on the top cover of the instrument. There are 4-pins Lemo compatible socket type ENB.0B.304 for Channels 13 and TNC for Channel 4, all with IEPE power supply for the accelerometers or microphone preamplifiers.

The microphone preamplifier SV 12L has the proper plug-in with the screw for direct connection with the instrument to the TNC connector (Channel 4) but it is recommended to use the preamplifier with any of the extension cables (i.e. SC 26) or the SA 08 gooseneck. The same type of the connector should be used to attach one-channel accelerometer to Channel 4. The SC 27 coiled cable is recommended in this case. In order to connect the SV 12L microphone preamplifier to Channels 13 one has to use the SC 49 cable (LEMO 4-pins plug to 3 * TNC sockets, 0.7 meters long). The SC 49 or SC 39P (LEMO 4-pins plug to 3 * BNC sockets, 0.7 meters long) cables should be used to connect one-channel accelerometer to any of the Channels 13. The triaxial accelerometers can be easy connected to Channels 13 by means of the SC 38 cable (4-pins Microtech to LEMO 4-pins, 2.7 meters long). It is recommended to attach the SV 25 dosimeter microphone with the integrated preamplifier and a cable to Channel 4.

Notice: Pay attention that the TNC connector should be always twisted to the light resistance but the LEMO connector is a push-pull only.

The full description of the signals connected to the sockets is given in the Appendix C.

The Ext. Pow. socket located on the bottom cover of the instrument is Marushin MJ-14 compatible socket, dedicated for the standard 5.5 / 2.1 mm plug (the right one in the Fig. above). The user can connect the external mains adapter (110 V / 230 V) which furnishes the proper DC level. The instrument can be charged from the external DC source (6 V / 500 mA DC 15 V / 250 mA DC). The current consumption depends on the voltage of the power supplier.

The additional input / output socket, called I/O, is 1-pin LEMO compatible socket type ERN.00.250 (the left one in the Fig. above). The function of this socket can be selected from menu (path: MENU / SETUP / EXT. I/O SETUP / MODE). The socket can be used as: analogue output with the signal from the input of the analogue / digital converter (before

the correction); this signal can be registered using magnetic recorder or observed on the oscilloscope (the ANALOG setting)

digital input for external interrupt (the DIGITAL IN setting) digital output for external trigger (the DIGITAL OUT setting)

Notice: Switch the power off before connecting the instrument to any other device (e.g. a printer or a Personal Computer).
